The invention discloses a process for dyeing a silk interwoven jacquard fabric, belonging to the field of silk interwoven jacquard fabric dyeing technology. The process comprises the steps of dye fixing, primary washing, soaping, secondary washing and cylinder discharge and drying, wherein in the dye fixing step, the pretreated silk interwoven jacquard fabric is put into an active dye solution and dyed by adopting a jig dyeing method at 80-85 DEG C for 60-200 minutes; the active dye solution is obtained by mixing 1-5% owf of lanasol dye, 1-5% owf of HE type dye, 20-50g / L of anhydrous sodium sulphate, 5-20g / L of sodium carbonate and water. The process disclosed by the invention can be used for realizing bath dyeing when silk fibers and cellulose fibers in the silk interwoven jacquard fabric are dyed with different colors respectively, the color fastness of the obtained silk interwoven jacquard fabric with the double-color effect can reach the two-bath dyeing fastness, meanwhile, energy is saved, emission is reduced, and the process time is obviously shortened.

The invention provides a preparation method of high-purity boric acid. The preparation method comprises the following steps: putting industrial boric acid into a mixed solution of circulating mother liquor and trace inorganic acid, stirring, and heating for dissolution; performing thermal reaction for 1-2 hours in a temperature range of 80-95 DEG C; cooling to obtain wet boric acid crystals; respectively washing the crystals by virtue of mother liquor alternately purified by a cation exchange resin column and an anion exchange resin column; and drying to prepare high-purity boric acid. Compared with the prior art, the technical scheme provided by the invention has the technical advantages of being simple in process flow, having no environmental pollution, being high in crystal purity and low in manufacturing cost, selecting between granular or lamellar crystals, and the like; moreover, the crystal particle size distribution can be greatly improved.

The invention discloses a government service system based on the Internet, comprising a data acquisition module, a request receiving module, a database, a government service module, and a data management module. The data acquisition module is used for acquiring information of an area under administration and storing the information in the database. The request receiving module is used for receiving a request input by a user side and sending the request to the government service module. The government service module is used for pushing policy information to the user side, making the data management module process data according to the request input by the user side, returning the processing result to the user side, and storing the processing processes of all events in a log. The beneficial effects are as follows: grass-roots government service matters are processized and electronized online, online application, acceptance, examination, decision and delivery are realized, the handling time is shortened, and the cost of service is saved for enterprises and the masses; and a public participation mechanism is established, satisfaction evaluation is carried out, and convenient comprehensive service is provided for the masses.

The invention discloses a dyeing technology for carrying out one-bath scouring and dyeing on a lycra-containing cotton knitted fabric by active turquoise blue, mainly aims at solving the problems that a traditional technology is relatively large in water consumption and coal consumption, long in technology duration and high in power consumption. The dyeing technology comprises the working procedures of preshaping, stitching the edge, carrying out one-bath scouring and dyeing, and carrying out aftertreatment and afterfinish in sequence, wherein in the working procedure of the preshaping, a chelating agent, a deoiling agent, tea saponin, a tea saponin dispersion dispersion liquid and a scouring agent are fed; in the working procedure of the one-bath scouring and dyeing, the deoiling agent, a defoaming agent and refined enzyme are fed into a dye vat after being diluted by clear water, a leveling agent, anhydrous sodium sulphate and sodium carbonate are fed into the dye vat in a way of circulating material injection, the active turquoise blue and urea are fed in a way of dissolving the materials by the clear water, and the heat preservation is carried out at the temperature of 80 DEG C. After the dyeing technology is adopted, the lycra-containing cotton knitted fabric can be bleached, dyed and scoured by the working procedure of the one-bath scouring and dyeing, so that a plurality of tasks can be completed in one working procedure, the technological process is shortened, the processing steps are reduced, and the water consumption, the electricity consumption and the coal consumption in the processing steps can be omitted.

The invention discloses an efficient sewage denitrification process which comprises the following steps: converting a part of ammonia in ammonia-containing sewage into nitrite by aerobic nitrifying bacteria in an aerobic tank; introducing sewage treated in the aerobic tank into an anaerobic tank; and converting ammonia and nitrite into nitrogen by anaerobic ammonium oxidizing bacteria in an anaerobic tank. The invention has the beneficial effects that the solution converts a part of ammonia into nitrite by aerobic nitrifying bacteria and then converts the remaining ammonia and nitrite into nitrogen by the anaerobic ammonium oxidizing bacteria, compared with a traditional treatment method, when treating the same amount of sewage, the solution takes less time for nitrification in the aerobictank, consumes less oxygen, and can reduce energy consumption of aeration, shorten process time and reduce construction and use costs of the aerobic tank; the anaerobic ammonium oxidizing bacteria can be used for simultaneously treating ammonia and nitrite so as to improve denitrification efficiency at an anaerobic stage, thereby shortening the time for the entire denitrification process.
